AUTOMATIC CUT-OUT FOR TYPOGRAPHICAL MACHINES.

Application filed May 27, 1921.

To all y107mm 'z' may concern:

Be it known that I, EDWIN XV. PinnsoN, a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented new and useful Improvements in Automatic Cut-Outs for Typographical Machines, of which the following is a specification.

The present invention relates to improvements in typographical machines of the linotype class wherein the operations of conveying an assembled line of matrices to a mold and the casting of a type bar or slug therefrom are performed periodically, or following the composition of each line by the operator, the continued operation of the machine, after each casting operation distributing and returning the matrices used in each line, to the magazine.

Machines of this class are commonly driven by electric motors, each machine being provided with a motor which is individual thereto and runs continuously while the machine is in use, and a manual switch is 'provided by which the operator may start and stop the motor, when the use of the machine is commenced or terminated. Practice has shown, however, that the usual manual switch for starting and stopping the motor does notv secure the desired economy in the consumption of electric` current, nor does it avoid unnecessary wear on the machine, in the routine of workv in a composing office where the operators; frequently leave their machines for longer or shorter periods of time and neglect to operate the usual manual switch to cnt off current to the motor and the lights on the machine. The expense incurred on this account, especially where as is usual, a large number of machines is employed, is a substantial loss.

The object of the present invention is to provide means for automatically cutting off current to the motor and also, if desired, to the lights used in the machine, in the event that the operator leaves the machine for a period of time longer than that required for the distribution of the matrices used in the line from which the last cast was made, thus ohviating the objections which practice has sl wn to exist Where the Ordinar7 manual switch is employed to startand. stop the rnc-tor. The automatic current cut-0H proyided by the present invention does not interfere, however, with the continuous oper- Specification of Letters Patent.

ation of the 'motor While the machine is operating regularly in performing its usual functions of delivering the lines of matrices to the mold and the casting of type bars or slugs therefrom, although it will operate with certainty to cut off the supply of current after ya suitable period of idleness has elapsed following the casting of the last type bar or slug.

To these and other ends, the invention consists in certain improvements and combinations and arrangements of parts, all as will be hereinafter more fully described, the features of novelty being pointed out particularly in the claims at the end of the specification.

In the accompanying drawing Figure l is a side elevation, partly in section, of an automatic cut-out constructed in accordance with the present invention and applied to a line casting machine of the Y linotype class;

Figure 2 is a front elevation of the device, partly in section, showing the controlling connection between the cut-out and metal pot of the machine; and V Figure 3 is adetail perspective view of the switch which controls the supply of electric current to the machine.

Similar parts are designated by the same reference characters inthe several views.

The present invention is applicable generally to electric-metor-driven typographical machines of the linotype class, as shown and described generally in the patent granted to Ottmar Mergenthaler, No. 436,532, dated Sept. 16, 1890, and to any other electric-motor-driven typographical machine employing a similar cycle of operations. The preferred embodiment of theinvention is shown .in the accompanying drawing and will be hereinafter described in detail, but it is to be understood that the invention is not ren stricted to the .precise construction shown and described, as equivalent constructions are contemplated and these will be included. within the scope of the claims.

In the present instance, the cut-out mechanism is supported and substantially enclosed within a housing l which may be suitably mounted or supported on the framework` of the machine. In the present instance, the housing is supported at its lower end by the part of the frame designated 2, by a screw Bwhich extends through said part said full line position, after it has been adof'the frame and-is threaded into a lug 4 which projects from the bottom ot the housing, and a set screw 5 threaded in the lug` 4 bears against the part of the frame 2 and serves as an adjustment to position the housing and the cut-out mechanism enclosed therein, with respect to the part ot the operating part of the machine from which the cut-out mechanism is driven. The upper portion oi" the housino' may be supported or braced by a bar 6 which is secured to the housing by the screw 7 and this bar may be attached to an adjacent part of the stationary frame of. the machine;

The cut-out mechanism comprises a screw VS which is journalled at its ends in the front and rear walls of the housing and a slide or carriage 9 lwhich is mounted to travel in parallelism with the axis 0i' the screw and carries a blade or tooth 10 which is shaped and'arranged to engage the threaded portion of the screw,sc'that while this toot-h is engaged with the-revolving screw, the carriage will be shifted in a direction trom the 'full line position, toward the dotted line position, Vas shown in Figure 1. The carriage is also movable in a direction transversely of the .screw to cause engagement or disengagement of the tooth or blade 1() relative y to the screw.V Preferably and as shown, the carriage is mounted to slidelongitudinally on a squared, or other suitably shaped rock shaft '11, the ends ot which are rotatably journalled or supportedby the housing. A tension spring 12 attached at one end of an arm 13 which projects laterally from the rock shaft 11 and fixed at its other end to a hook or eye 14 on the casing, acts with a tendency to swing the carriage 9 toward the screw and to engage the tooth or blade 10 thereon with the threaded portion oil the screw, so that the revolving motion ot the screw will act to advance the carriage in the direction above described. A tension spring' 15 attached at one end `to the stud or projection 16 on the carriage and at its opposite end to the stud or projection 17 on the rock shait 11, acts with a tendency to yieldingly hold the carriage in the `full line position shown in Figure 2, and to restore the carriage to the ,'vanced to or toward the ldotted line position (Figure 1) and then displaced to disengage the tooth or blade 10 thereon from the screw.

'The carriage controls the supply ot electric current to the electric driving motor of the machine and preferably also tothe lights, when such are used vin the machine. In the 'present instance, a switch is employed, the terminals y18 and 190i which are adapted to be bridged by a switchA plate or member 20, to complete vthe electric 'circuit through which the electric current issupplied to the "electric driving'rnotor vand theMlights. The

terminals 18 and 19 are preferably XeCl to an insulating base 21 which is suitably secured in stationary position within the housing by the screws 22. The switch plate or member 20 may, as shown, consist ot a strip of flexible metal, one end ot which is iixed by the screw 23 to one ot the terminals, the terminal 19 in the present instance, while its opposite end 2e has a normal tendency to engage the terminal 18, but may be moved or pressed out ot engagement therewith, by

the carriage 9 when the latter has been afdvanced to a Suiiicient extent by the screw 8. The controler the switcn member 20 by the carriage 9 is effected, in the presentinstance, by the projection 25 which may be composed ot fiber or other suitable insulating material secured to the carriage 9, this projection being so arranged that it is located'in line with the switch member Q0 when the carriage occupies a position with its tooth or blade 10 in operative engagement with the screw, but

member 20, andthe latter will' then complete. Vthe circuit between t -e terminals 18`and 19; and whenthe carriage 9 has been advancedby the screw to 'substantially the position shown by the dotted lines in 'Figure 1, the switch-operating projection 25 will have reached a posit-ion where the movable end 2li4 ot the switch member is disengaged 'from the terminal 1.8 and the circuit through vwhich electric current is supplied to the machine,

If'the carriage 9 yis swung laterally in a direction away tromV will then be interrupted.

the screw 8 while'the carriage occupies the dotted line position represented in Figure 1, the projection 25 on 'the carriage will be withdrawn laterally from engagement with the switch member 20, thus permitting the latter to snap into engagement with the terminal 1S andtliereby reestablish the electric circuit through the machine and by this same operation, the tooth or blade 10 on the car-r riage will be disengaged fromA the thread ot the screw and the spring 15 will act automatically to restore the carriage to the full lines position shown in y,l `i,e,'ure 1. A handle or lever 26 is preferably fixed to the Jforward end oi" the rock shaft 11 to provide means 'lf'or manuallyrocking 'the sh aft 11 to trip the Y switch and to restore the carriage to its retracted'or initial position. thus enablingthe operator to start the machine into operation after its operation has been interrupted by the cut-out. According to the present invention, the cut-out will automatically interrupt the operation of the machine when the latter ceases to perform its periodic cycles with theusual regularity, or in other words, where an abnormal period of time ela'pses after the completion ol one cycle ot operations and the repetition of such cycle of operations. This result is attained by causing the screw 8 to revolve in unison with a suitable continuously-mnuing part of the machine and tripping or releasing the carriage 9 periodically by a suitable part of the machine which iarticipates in the periodic cycle perormec by the machine. In the present instance, the screw 8 is driven preferably by the intermediate shaft 27 which, in machines ot the linotype class, revolves continuously while the electric-driving motor is running and it serves to drive thev continuouslyrunning distributor. kFor the purposes of the present invention, this shaft may have a screw or worm 28 fixed thereon, this screw or worin having a single thread 29 and the screw or worm engages a tooth Vor worm wheel 30 which is iiXed to the screw 8, the latter being thereby driven in a direction to cause the carriage 9 to advance from the initial or full line position to or toward the dotted line position shown in Figure 1, while the tooth or blade 10 on the carriage engages the thread of the screw 8. A

Tripping or releasing of the 'carriage to cause its return to initial position is preferably controlled by the advance of the metal pot toward the mold, preparatory to the performance ot a casting operation. As shown, the metal pot 31, which corresponds to the metal pot usually employed in typographical machines of the linotype class and which approaches and recedes relatively to the mold.v incidental to each casting operation, is provided with a cam or wedge 32 at one side and a roller 33 carried by a rcciprocatory bar 3-1 rides on the cam or wedge 32, the advance of the metal pot toward: the mold causing the bar 34 to shift toward the right, as shown in Figure 2, while the 'receding movement of the metal pot permits the bar 3a to return toward the left. The bar` 34 is suitably guided by the frame of the machine and it is pivotally connected at one end'to the lower end of lever 35, the latter being pivoted at 36 to the part ofthe frame 2 and the upper end of this lever is provided with a linger 37 which is arranged at one side of an arm or projection. 38 which is fixed to the roclrshaft 11, the finger 37 being'fcaused to engage the arm 38'and to rock the shaft' 11 into the position shown in Figure 2, thus tripping the carriage `9 by disengaging its tooth or blade 10 from the thread'of'lthe screw 8, when the metal pot advances-'relatively to the mold, preparatory to a casting 4the'rnold to cast a type baror slug,'to adoperation, the finger 37, however, being clear of the arIn 38 after the metal pot has receded from the mold and the spring 12 has restored the lever 35 and the bar 34 to their initial position.

The mode of operation of the cut-out here- -in shown and described, is briefly as follows zv Y To start the machinein operation, the handle or lever-26` is manipulated to swing the carriage 9 laterally into the position shown in Figure 2, this operation disengaging the tooth or blade 10 on the carriage from the thread of the screw 8 and causing the restoring spring 15 to return the 'carriage to the initial position shownl by the full'lines in Figure 1. By this operation,

the switch member 20 is caused to bridge vcarriage which isnormally held in operative engagement' with the thread "of the screw 8, by the spring-12, then causes the carnage 9 to advance from the-full line position towardthe dotted line positionA (Figure 1). During the first part of the advancing movement of the carriage 9, the operator is assembling the matrices to form a line. or if aline has already been assembled,such line Vis caused to advance to the castingmechanism, this being the first part of a period-` ically or intermittently performed cycle which isinitiated by the operator who releases a clutch and'setsinto operation mechanisms for justifying the line, for positioning v'ance'jthemetal pot'l'up tothe mold, tooperate'the pump to' injectrmetal from the metal peti-nto the mold and' to restore these tory to a casting operation, will cause deflection of the carriage 9'ina direction away from' the screw 8, thereby tripping Vor refelcinents 'to "their normal positions, aftery which theline of matrices from which the leasing the carriage with respect to the screw, with the result that the carriage 9 is returned or restored to its initial position by the spring l5. The alternate advance of the carriage 9 by the screw 8 and its tripping and return by the advancing movement of the metal pot will takeplace at intervals which will be determined by the time elapsing .between two successive casting operations, but 'if thev casting operation is not repeated within the period of time for which the cut-out is set, the carriage 9 will continue its advance by the screw 8, without being tripped, and thev projection 25 on the carriage will engage the switch member 20 and force its upper end 24 out of contact with the terminal 18 of the switch, thereby interrupting the motor and light circuit. This action, for example, would take place should the operator leave the machine witheration for a suilicient length ofrtime after thel operator may leave it, to enable the machine vto automatically dispose of the last Y line assembled and to distribute all of the than the one shown. `the cut-out 'is shown and described herein as Y fI" claimas lfmy invention machines ofthe class-employing.electric curlmatriceswhich may have been used in such operation, into `the magazine. The `machine -may be instantly restarted when desired, by rotating the handle or lever 26 to cause -release lof the carriage from the switch `and screw.

Obviously, any suitable or well known de-l v vices may lbe used t0 minimize or prevent sparking or burning of` the switch contacts and it will lalso be understood that any suitable -form of switch ma' be employed other iliu'rthermore, while controlled vby the metal pot, any other part of the machinewhich operates within the periodic cycle thereof may be utilized as a i relatively to the switch.
